Well I am having questions about the big 3 upgrade and running into some problems. I will soon be running Two Level 3 DC 10s in my truck on a DC 2k or a crescendo 2k. Okay where to start Here is the list of things i am going to get for the upgrade if you guys know of any better things or better prices please let me know. http://www.amazon.co...=A3J1PF183V710G http://www.amazon.co...4163658&sr=1-16 http://www.amazon.co...4163658&sr=1-16 http://www.amazon.co...cp_ob_e_title_2 And i am missing a few items i will have pictures of them if you guys could tell me where to get them and the size. first off here is a picture i have a question with Can i attach the terminal on top of the previous one i have right there the stock red one or do i have to get a different terminal? OR could i possible get aways with two simple ring terminals where that old one is? What would be best what should i do? Next Picture and question is where can i get this one of my buddies gave me it and i can't find out where to get it and what size it is. NExt question is i have a ground going off the negative of the battery and under the engine block i believe and i am wondering if i should run my new zero gauge where that is going or make a new connection on another spot and take that wire out? seen in this picture Next picture is is a little red box that gets power from the positive of the battery and houses power to my alternator and then runs down underneath my engine and i don't know where it goes because my truck is so low i can't get underneath and am wondering if anyone has a idea where it goes and if i should get rid of the box and just run wire everywhere or keep the box and use it for the zero gauge. Also i am wondering what size ring terminal is best for the alternator i am having trouble finding a small enough one. And with the alternator some people are saying put a fuze on the line going from the positive of your battery to the alternator i am wondering if i should do that or is it not necessary? And the last question here is a pic of my distribution block i believe and it splits the power from my sub amp to my mids and high amp and i am wondering where can i get one that will work with my zero gauge? also my mids and high amp only allows eight gauge is there a block that can allow a 0 gauge output and 8 gauge output. sorry if its confusing here is a pic of it right now i can explain more if you have questions. and last last question on the positive going back to my amp how far away should my fuze be? and will i need any more in other places? well thanks for going through this long question i just want to make sure its right i do it all right i want to do it myself because i want to learn how to do it. i will reply if you guys have any more questions and please let me know if i am missing anything.!
